Greetings from Lancaster! My suggestion to you is that you write a business plan. There are also small business councilers to help you to do this. It is not an easy thing but a must for any entrepreneur. I went through the couciling and also took a few courses about business that were free. Did you know that a majority of businesses are small? So good luck. When you start out small it might be good to sell your product in a small market situation. Check out all of your competitors and see what you can do that they don't.
Good luck to you.
oh and btw - have you seen the doggie treats at Petsmart. They are very attractive and look like desiger christmas cookies. Of course they appeal to yt owners...we just love our babies
